Summary
In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: wake linked drain waiters on unlink snd_pcm_drain() on a linked stream parks an on-stack wait entry on the drained peer's runtime->sleep, and after schedule_timeout() removes it only if that peer is still found in the caller's group. If group membership changes during the wait and the sleep ends by signal or timeout (so autoremove_wake_function() does not run), finish_wait() is skipped and snd_pcm_drain() returns with the entry still queued on that stream's sleep list; a later wake_up() then walks a freed stack frame. This is reachable by unlinking either the drained or the draining stream. Unlike the close path (snd_pcm_drop() -> snd_pcm_post_stop()), snd_pcm_unlink() never wakes the sleep queues. Wake every group member under the group lock before the membership change, so a linked drainer is released and drops its entry while the streams are still grouped. The window was opened when snd_pcm_link_rwsem stopped being held across the wait and the removal became conditional on group membership (see Fixes). The later switch to finish_wait() kept that conditional removal, so the signal/timeout case remained.

snd_pcm_kernel_ioctl does not expose LINK/UNLINK, and there is no network-facing path to this code.\\nAC:L - This is a race, but the attacker controls both sides by opening two PCM fds, linking them, blocking one thread in DRAIN, and concurrently UNLINKing or closing the peer; sending a signal or waiting for timeout forces the path where finish_wait() is skipped.\\nPR:L - Exploitation requires only a local process able to open and ioctl ALSA PCM nodes (typical desktop/mobile users via the audio group, session ACLs, or equivalent device permissions); no real root, CAP_SYS_ADMIN, or init-namespace privileges are needed.\\nUI:N - The attacker drives the entire sequence programmatically with their own PCM file descriptors and threads; no victim interaction such as opening a file, mounting a filesystem, or plugging in hardware is required.\\nS:U - Impact is confined to kernel memory corruption and privilege escalation within the same security authority; this is not a VM escape, IOMMU/DMA boundary bypass, or other cross-scope violation.\\nC:H - The orphaned wait_queue_entry_t remains on the sleep list after snd_pcm_drain() returns, and a later wake_up() dereferences a freed on-stack wait entry (use-after-free), which can expose kernel stack/memory contents under attacker-controlled timing.\\nI:H - Corrupting the wait-queue list with a stale stack-backed entry gives kernel memory corruption primitives; wake_up() invokes the entry\u0027s function pointer from freed stack memory, enabling plausible control-flow hijack and arbitrary write via further heap/stack grooming.\\nA:H - A subsequent wake_up() on the poisoned sleep queue walks a freed stack frame and can oops or panic the kernel; even without full exploitation, the UAF reliably threatens system availability on multimedia desktops, kiosks, and embedded devices with ALSA access.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"c172e4c53321ee6429955295ea133bc3597a3ca9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"3035bb784cea3f338934f5042dd3f35225a51b2e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"1c1b7e8e545ce65e40f65b55c432765e058ea98f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"e8b784a3f4fba3ea9c4d05138ecfa784a069627f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"e8315330e4ec09c0cac625515400e13d0ee22b81\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"2940cc3cf43c72126b74ee6376314c195382023a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"db09bc4ab19ce548a078240d2374792523953500\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f57f3df03a8e6010e321fa0258d3e054713c3cb7\", \"lessThan\": \"f495b6c4c8594122918552c9be2b51eb71647cd9\", \"versionType\": \"git\"}], \"programFiles\": [\"sound/core/pcm_native.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.1\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.1\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.265\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.216\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.183\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.151\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.103\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.44\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.8\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"sound/core/pcm_native.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/c172e4c53321ee6429955295ea133bc3597a3ca9\"}, {\"url\": \"https://git.kernel.org/stable/c/3035bb784cea3f338934f5042dd3f35225a51b2e\"}, {\"url\": \"https://git.kernel.org/stable/c/1c1b7e8e545ce65e40f65b55c432765e058ea98f\"}, {\"url\": \"https://git.kernel.org/stable/c/e8b784a3f4fba3ea9c4d05138ecfa784a069627f\"}, {\"url\": \"https://git.kernel.org/stable/c/e8315330e4ec09c0cac625515400e13d0ee22b81\"}, {\"url\": \"https://git.kernel.org/stable/c/2940cc3cf43c72126b74ee6376314c195382023a\"}, {\"url\": \"https://git.kernel.org/stable/c/db09bc4ab19ce548a078240d2374792523953500\"}, {\"url\": \"https://git.kernel.org/stable/c/f495b6c4c8594122918552c9be2b51eb71647cd9\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nALSA: pcm: wake linked drain waiters on unlink\\n\\nsnd_pcm_drain() on a linked stream parks an on-stack wait entry on the\\ndrained peer\u0027s runtime-\u003esleep, and after schedule_timeout() removes it\\nonly if that peer is still found in the caller\u0027s group.
